If "The sum of the squares of a triangle's two sides equals the square of its longest side", then the triangle is a Right Angled Triangle.

In this case the above is not true, so clearly the triangle in question is not a Right Angled Triangle.

Therefore, 90 cannot be an angle of the triangle.

Answer is D

since the sides of the triangle is not equal to the third side then the triangle is not a right triangle and hence the angle cannot be 90 degrees. So the answer is D
